Application med December 29, 19'2'6'. seriai No. 157,182.'

Y This invention relates -toa floor gas fur- 'nace and heating apparatus' having therein essential features which will adapt to be used as a hot air pipeless furnace,

apart of the improved` byvan addition to structure,.as a hot the same and air pipe furnace. f

The primary object of the invention is to provide agas furnace -or of the class specified which ly effective as a heating means and to be installed or tion by suspending the same medium of a floor and constitutinga part of the heater,`an

he-ating apparatus is advantageousadapted set up in operative posithrough the register of a novel form whereby a reliable'and easy disposition of the furnace or heating apparatus ensues, the

furnace or apparatus being readily interi-v orly accessible and controllable when necessity requires.

A further object of the inventionJ is to generally improve ratus embodying few number of burner or vent cha are partially pro chamber in which a vgas furnace or appatherein' a comparatively components including a mber wherein the burners jected and a combustion the said inner vent chamber is located together with an airheating chamber embodyin g a corrugated wall structure surrounding the said combustion chamber and having communication with. an exterior fresh air supply through the medium of which currents of cold air are directed to the lower terminal of the heating chamber having the corrugated wall as well as with lower currents' of c wardly to the bottom of chamber and com old air passing first` downthe said air heating mingling with the fresh air from the 'exterior and then passing upwardly through th nace in a heated e a'irheating chamber for directly above the furcondition, and in' one of the forms having means provided therein to supply the 'heated a distance from air to other compartments the furnace with a steady and reliable supply. y A

A still further object of the inventionis to provide a gas furnace on heating appaembodying therein a combustion chamber in which is located the remaining being at all times el 'form includin a pilot burner members, the latter observable from the top In the drawings:

Fig. 6 is aperspective view of a furnace also embodying the features of the invention, and having the hot air conveying pipes and accessories incident thereto eliminated. The numeral' 5 designates an enclosing casing including a base 6 with a depending flange y7, the said base having an opening 8 therethrough. The casing 5 is secured at 'its upper end to a register 9 having a cenf v egister structure and burner omitted and device and removable cap there or tral removablesection 10, preferably of' circular contour, and removable corner sections 1.1, which render the interior of the improved furnace or'heating apparatus readily accessible. The register is, surrounded by Alan outwardly and downwardly inclined or outwardlyl flared supporting flange 12, which has its edgeresting upon a floor 13 around a suitable register opening, mg wholly located above and supported on the ioor 13 and vserving asthe sole means for suspending the casing 5 and parts enclosed thereby. The casing 5, base 6 and register 9 will be formed of durable material, preferably' metal, and vsuitably secured to provide a tight enclosure. The manner of securing the metal used in the constructonof the enclosing casing may be varie'd as. desired, and while it is preferred that the improved heater be suspended yby the the register beico `base 6, andv whereby the burner an floor register as just explained, it is obvious that the same may be practicably supported in operative position by other means. -At the upper part of one side of the casing is a heat distributing chamber 14 having a box-like enclosure 14a constructed of sheet metal with .a 'partition plate l5 extending therethrough and peripherally jointed as-at 15a, said partition plate having an opening 16 of such dimensions as to permit heat cur* rents to pass into the chamber and be distributed fromthe latter by means of suitable pipes connected to collars 17 projecting outwardly from the front side of the said boxlike enclosure and leading oli' to various heat lines for conveying the heated Vair currents to the compartments or rooms ot a building. Y

i To assist in the circulation of the heated air currents coming through the opening 16 into the chamber 14 by, way of the vplpes leading off from the collars 17 to various compartments or rooms, a bladed fan 18 is' installed andsuitably driven, as for instance by an electric motor 18a, to which current is supplied by means of wires 20 Afrom any suitable electrical source. The box-like enclosure for the chamber 14 is appliedto the side 5B of the. 4casing 5. The top. wall 21 of the chamber 14 Icontinues inwardly to the top 22a of the 4interior chambered structure 22, having a rear curved edge 23, from which depends an inner vertical curved wall i 24, an opening25 being formed in the bot'- tom of this supplemental chambered structure, as clearly shown by Fig. 3. The top 22a of this supplemental chamber 22. is loycated directly under and at a distance from the register 9, and rises at an elevation above the top of the said'in'terior structure of the furnace or heat-ing apparatus and far enough below the said register to avoid interference with the placement and removal of the parts of the latter. The bottom wall 21 of the chamber 14 continues inwardly to the upper portion of the interior furnace structure. I

. Within the lopening 8 of the base 6 a circular burner lor vent chamber 26 is mounted and formed fully open at the top 27 and bottom 28. -This burner chamber rises from or forms a part of an annular baseor ring '29, which is located below the plane of the base 6, as shown by Fig. 3, and concentric therewith-is a combustion chamber 30 having' a. surrounding wall 31 provided with lower outer angle fastenings 32, whose horizontal members rest on the base 6 and are secured to corresponding fastenings 32 by short nutted bolts 33, which extend throu h'the combustionv chambers 26 and 30 are positively 'united and sustained in proper relative positions.l .The annular 'base 29 is in the o of a recessed ring with an upwardly projecting surrounding ange 34, and by this' means the lower end. of the wall 31 of the combustion chamber 30 is further supported upwardly from the collar 36 a suitable dis-l tanceY and has anupper exteriorly screwthreaded end with a removable cap' 39 holding or carrying therewith a transparent plate or mica covering 40, as shown by Fig.v

3. The top closure 22 has an opening 41 formed therein through which, the -upper screw-threaded end 38 of the tube 37 projects to render the cap 39 accessiblethrough the register 9 above.

In the annular ring 29 an opening or slot 42 lis formed which communicates with a correspondingly shaped opening or slot 43 at the upper end of a chambered coupling box 44 secured closely againsty the underside of the annular base or ring 29 and located fully below the'latter, said chambered coupling box. having a galvanized iron vent pipe 45 appliedthereto as shown, and running to a chimney flue or other means of escape for the products of combustion. lVithin the burner or vent chamber 26 it is preferred to'install the burner structure disclosed by my pending application Serial No,

126,533, tiled August 2, 1926.- These burners yextend Yonly partially, ora comparatively short .distance downwardly into the said burner or vent chamber 26, the latter chamber serving mainly as avent chamber. This burner structure comprises a manifold or base chamber 46 from which a plurality of circularly arranged burner tubes 47 extend upwardly, said burner tubes being formed with upper closed ends and orifices 48 at a suitable distance b elow the same as well as lower transverse air passages 49 contalmng a suitable gas burner spud, and interiorly located -with relation to this'I group of b urner tubes isA a pilot light or tube 50, which is suitably apertured as at 51 and closed at they top. On top of the pilot light is a canopy orms,` an upor spreader 52 at a distance above the upper closed ends of the tubes 47, -all as clearly disclosed in my pending application above noted., The burnertubes 47 and pilot light 50 are suppliedwith gas by separate supply pipes 53 and 54, respectively commi'mlcatingv with the manifold 46 and the said pilot light or burner 50 and united as at 55 land then continued in single form through a union box 56 to a main or other source of supply. Valves 57 and 58 are located inthe pipes 5.3

and 54 adjacent the box '56 and at the point where the two pipes unite and are respectively controlled by value-.operating rods 59 and 60 extending upwardly through the in- 'wterior of the furnace orvheating apparatus y and accessible at' the floor register 9, as

shown, and may be readily manipulated to first supply gas or fuel to the'pilotburner 50 and at which time the rod 6() is operated to open the valve 58 and the rod 59'operated to close the ,valve 57. The pilot light or burner 50 is ignited through the tube 37 by 'removing the cap 39, which is made accessible by first withdrawing the central grated l burner tubes 47 ensues, the pilot light 50 is kept burning, or extingulshed .by suitably manipulating the valve 58 through its operating rod 60. The1 burner tubes .47 and pilot light project above the upper terminal of the burner chamber 30 as 'shown by Fig. 1, and the canopy or spreader 52 is also located at some distance above the .upper termination ofthe burner chamber 'so that the heating function of the burner including the group of tubes 47 will be serviceably practicable. The pipes 53 and 54 extend down vertically from the manifold 45 to the bottom terminal of theburner chamber 30 and then pass out horizontally under the lower end of the said burner chamber and also under the annular base or ring 29 to the box 56 as heretofore explained.

Surrounding the combustion chamber is a series of angular heat radiating -corrugationsl, and surrounding these corrugations is a circularv wall 62 forming an outer heating chamber 62, which terminates at its u per open end within the .opening 25, as at t e bottom portion `of the'supplemental chamberedcasing 22 of the furnace shown by Figures 1 to 5 inclusive.- The outer side of the circular wall. 62 of the heating chamber 62'* is sheathed by an asbestos covering 63,- it be- -ing seen, by reference to Fig. 3, that the bottom of this chamber 62 is fully open and that the said wall and angular corrugations 61 'terminate at a. distance above the base 6, to give amplespace for the upward circula-1 tion or movement therethrough of the currents of cold air. The upper part of the wall 62 extends through the opening 25 in the bottom of the supplemental chamber casing 22, as 'heretofore indicated, and thus there is no interference with the upward rise of the currents of heated'air into the said chambered casing. The heated air currents which circulate through the chamber 62,

into the chamber 14 through the opening 16 vof the partition 15 for distribution to various parts of a building through thev medium of the pipes heretofore described and connecting with the collars 17. The cold air adjacent the, floorvpasses downwardly through all parts "of the register 9,` in this structure, to the lower limit of the outer heating chamber 6.2a between the outerasbestos-covered wall 62 and the walls of the casing 5, and mingles with the cold air admitted I5 from the exterior by'a pipe connected to a collar 64 surrounding an inlet opening 65, aud mingles with the cold air thusadmitted -through the said inlet and then passes upwardly through the heating chamber 62fan-d becomes heated, and then passes into thecasing 22 for distribution -as heretofore explained, it being intended that fresh air'will be taken lfrom the exterior of the building in which the improved furnace is insta-lle The cold air passing downwardly from the exterior, as just explained, also becomes beated by passing upwardly within the outer chamber 62a in contact with the angular corrugations 61.

The furnace as shown by Figure 6 is of a pipeless, gravity nature, and embodies all the interior furnaceelements heretofore described except the chamber '14 and the boxlike enclosure, 14 defining-'said latter chaniv ber together with the fan land the suppley mental casing defining the chamber 22a. T he outer heating chamber 62b in 4this second form of the furnace'extends fully to the cen- 'tral circular lmember 10 of the register 9,

and from this 'member 10 the heat' currents,

rpass .upwardly into a compartment or roomsimilar to the first form of furnace heretofore described, and the same reference char! acters are applied thereto.

From the foregoing it will be seen that the 'products of combustion from the. burner chamber 26 in both furnace structures are carried off by way of the slot 42 and pipe -45- into 'a ue, 'which may be located at a disltance from the furnace or .heating apparatus.

Furthermore, the outer heating chamber 62 andthe temperature of the cold air is materially increased by the yradiation issuing from the wall surroundingthe inner heating chamber 30 and the angular corrugations 31.

In the firstform of the furnace, the fan, lo,-

cated mainly interiorly of the chamber 14",

causes the heated currents entering .this chamber to be forcefully driven through the v openings and outlet collars 17 surrounding the same intoand through the heat-convey- -`or. 62"- serves to thoroughly heat the cold air i passing upwardly through the said chamber,

ing pipes leading olf from the furnace or heating apparatus to different distributing points.-
